/* কার্ডগুলোর অনন্ত cardFloat animation (translateY) + .app-shell-এর perspective/preserve-3d মিলে
   ব্রাউজার প্রতি ফ্রেমে scrollable overflow সামান্য বদলে ফেলছিল — ফলে নিচের হরাইজন্টাল স্ক্রলবার
   কিছু না করলেও নিজে নিজে সামান্য নড়ছিল। পেজ-লেভেলে horizontal scroll কখনোই দরকার নেই
   (টেবিলের নিজস্ব .table-scroll আলাদাভাবে scroll হয়), তাই এখানে ক্লিপ করে দেওয়া হলো।

   এই একই bug-টাই SMTP Accounts floating window-এর ডান পাশের (vertical) এবং নিচের
   (horizontal) scrollbar-কেও নিজে নিজে নড়াচ্ছিল — window-frame আলাদা element হলেও,
   .app-shell-এর কার্ডগুলোর 3D transform animation পুরো ডকুমেন্টের scrollable-overflow বারবার
   রিক্যালকুলেট করাচ্ছিল, যার প্রভাব পুরো পেজের (এবং তার ওপরে ভাসমান windows-এর) scrollbar
   rendering-এ গিয়ে পড়ছিল। নিচে .app-shell-এ `contain: layout paint;` দিয়ে সেই
   recalculation-কে .app-shell-এর ভেতরেই আটকে রাখা হলো, যাতে বাইরের কোনো scrollbar
   (SMTP window সহ) সেটার প্রভাবে আর না নড়ে। */
